Description
Technical Field
[0001] This utility model relates to the field of equipment door connection technology, and in particular to a household appliance with a hinge assembly. Background Technology
[0002] In general, the doors of household appliances are connected to the cabinet via hinges, enabling them to open and close. Traditional hinge installation methods are quite cumbersome. For example, installing hinge components on a refrigerator requires the cabinet to be foamed, the door to be hung on the cabinet, the door to be opened, the hinge shaft to be installed in the trim sleeve on the door, and the positioning hinge to be adjusted to the designated position. The operator needs to hold the door while it is open and use screws to fasten the hinge to the front beam surface of the appliance. The entire process is inconvenient and difficult to complete alone. For doors that are heavy or have a large display area, one installer is needed to assist in holding the door while another installer is responsible for installing the hinge. Installation requires the cooperation of two people, which increases the manpower consumption on the production line, the difficulty and intensity of installation, and reduces production efficiency.

[0014] In one embodiment of the present invention, the second substrate is vertically connected to the first substrate, the reinforcing iron is provided with a slot that cooperates with the hinge clearance groove to allow the hinge substrate to pass through, the second substrate is provided to be connected parallel to the reinforcing iron and fastened to the side of the reinforcing iron facing the inside of the box.
[0015] In one embodiment of this utility model, the hinge base plate is integrally formed with the reinforcing iron and is formed by bending the reinforcing iron.
[0016] In one embodiment of this utility model, the reinforcing iron includes a main body parallel to the front wall and a folding plate extending perpendicular to the front wall toward the inner side of the box. The second base plate passes through the hinge clearance groove and is connected to the folding plate in parallel with each other, and is fastened to the bottom of the folding plate.
[0017] The beneficial effects of this utility model are as follows: The hinge assembly proposed by this utility model has a simple structure. By setting a hinge shaft plate that is perpendicularly connected to the hinge axis and a first base plate that cooperates with the hinge shaft plate, the hinge shaft plate and the first base plate are connected by a connecting assembly along the extension direction of the hinge axis. This ensures that the hinge connection is completed in the height direction of the door body, and there is no need to open the door body because the installation part is blocked by the door body. This makes it possible to connect the hinge without opening the door body for installation, reducing the complexity of assembling household appliance doors, improving on-site assembly efficiency, and reducing labor costs.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Please refer to them. Figures 1 to 9 The figure shown is a preferred embodiment of the present invention.
[0028] It should be understood that, unless otherwise expressly specified and limited, in this application, the terms “up,” “down,” “front,” “back,” “left,” “right,” etc., indicate the orientation or positional relationship based on the user’s facing side of the door of the household appliance being in front, and are used only for ease of description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed or operated in a specific orientation.
[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means two or more, and at least two.
[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "set", "connect", "connect", "fixed" and other such terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part.
[0031] This utility model provides a household appliance. Figures 1 to 9 An embodiment according to the present invention is shown.
[0032] like Figure 1 The household appliance 100 shown includes a housing 10, a door 20 for opening or closing the housing 10, and a hinge assembly 30 for pivotally connecting the door 20 to the housing 10.
[0033] In this embodiment, a refrigerator is used as an example of a household appliance. It should be noted that the household appliance 100 can also be other refrigeration equipment, disinfection equipment, or other household appliances connected by hinges.
[0034] The door 20 is pivotally connected to the housing 10 via a hinge assembly 30, so that the door 20 can pivot about the hinge assembly 30 to open or close the housing 10, and the door 20 and the hinge assembly 30 can remain relatively fixed in the vertical direction.
[0035] One or more hinge assemblies 30 may be provided as needed, and may be connected to the top, bottom or side of the front wall of the housing 10. In this embodiment, the hinge assembly 30 is described as being connected to the top of the front wall of the housing 10.
[0036] Please refer to Figure 2 and Figure 3 The inner side of the front wall of the housing 10 is provided with a reinforcing iron 5 parallel to the front wall. The reinforcing iron 5 can improve the stability of the hinge assembly 30 connecting the front wall of the housing 10 and enhance the ability to bear the weight load of the door 20.
[0037] The hinge assembly 30 includes a hinge main board 1, a hinge base plate 2, and a connecting assembly 3. The hinge main board 1 includes a hinge shaft 11 extending in a vertical direction and a hinge shaft plate 12 perpendicularly connected to the hinge shaft. The hinge base plate 2 includes a first base plate 21 that mates with the hinge shaft plate 12, and a second base plate 22 that connects to the first base plate 21 and mates with the reinforcing iron 5 on the inner side of the front wall of the housing 10. The connecting assembly 3 is used to connect the hinge shaft plate 12 and the first base plate 21 along the extending direction of the hinge shaft 11.
[0038] like Figure 2 As shown, in this embodiment, the hinge assembly 30 is separately provided with a hinge main board 1 and a hinge base plate 2. The hinge base plate 2 is connected to the front wall of the cabinet 10. The hinge shaft plate 12 and the first base plate 21 are arranged along the front and rear direction of the refrigerator. The hinge shaft plate 12 is perpendicularly connected to the hinge shaft 11. The connecting assembly 3 connects and fixes the hinge shaft plate 12 and the first base plate 21 in the vertical direction.
[0039] When the door 20 needs to be installed on the box 10, the hinge main board 1 is pre-installed on the door through the hinge shaft 11, and the hinge base plate 2 is pre-connected to the inner side of the front wall of the box 10. The pivotal connection between the door 20 and the box 10 can be realized simply by fixing the hinge shaft plate 12 with the first base plate 21.
[0040] In this embodiment, the second base plate 22 can be pre-connected to the inner side of the front wall of the housing with the reinforcing iron 5. The hinge shaft plate 12 and the first base plate 21 are then connected in the vertical direction outside the housing through the connecting component 3. There is no need to open the door 20 and hold the door 20 to adjust the positioning hinge component 30 to the front wall of the equipment housing 10. The hinge component 30 can be installed directly in the vertical direction with the door 20 closed, which reduces the complexity of production and installation and saves labor costs.
[0041] like Figures 3 to 5 As shown, the connecting component 3 includes a positioning structure 31 for positioning the connection position of the hinge shaft plate 12 on the first substrate 21, and a fixing structure 32 for fixing the hinge shaft plate 12 to the first substrate 21.
[0042] In this embodiment, the connecting component 3 is divided into a positioning structure 31 and a fixing structure 32. By setting the positioning structure 31, the connection position of the hinge shaft plate 12 on the first substrate 21 can be determined and pre-fixed, temporarily maintaining the relative position of the hinge shaft plate 12 and the first substrate 21. The fixing structure 32 is set for further fastening the connection, so that the surfaces of the hinge shaft plate 12 and the first substrate 21 that are in contact with each other are closely fitted to ensure horizontality.
[0043] like Figure 6 and Figure 7 The first substrate 21 shown has a first positioning hole 211, and the positioning structure 31 includes a positioning post 33 that mates with and is connected to the first positioning hole 211. (Refer to...) Figure 7 The positioning post 33 has a first positioning part 331 and a second positioning part 332 extending in the opposite direction to the direction perpendicular to the first substrate 21. The first positioning part 331 is disposed in the first positioning hole 211, and the second positioning part 332 protrudes out of the outside of the first substrate 21 to cooperate with the hinge shaft plate 12 for positioning.
[0044] In this embodiment, the first positioning part 331 and the second positioning part 332 of the positioning post 33 extend in opposite directions in the vertical direction. The first positioning part 331 is connected to the first positioning hole 211 of the first substrate 21, and the second positioning part 332 protrudes upward to the outside of the first substrate 21, which can help to accurately determine the position of the hinge shaft plate 12.
[0045] The hinge plate 12 has a main plate 121 that is parallel to and abuts against the first base plate 21 and partially overlaps the first base plate 21, and a second positioning hole 122 that is sleeved on the second positioning part 332 of the positioning post 33.
[0046] In this embodiment, the hinge plate 12 is partially overlapped above the first base plate 21, and the hinge plate 12 and the first base plate 21 are in close contact with each other and both extend in the horizontal direction. When installing the door body 20, it is only necessary to fit the second positioning part 332 through the second positioning hole 122 of the hinge plate 12 to pre-position the overall connection position and perform preliminary fixation. The positioning method is simple, requires no adjustment, and provides convenience for subsequent fastening connection.
[0047] Specifically, the first positioning hole 211 is provided with an internal thread 212, and the first positioning part 331 of the positioning post 33 is provided with an external thread 213 that mates with the internal thread 212, so that the first positioning part 331 is rotatably connected to the first positioning hole 211, and the diameter of the second positioning part 332 of the positioning post 33 is larger than the diameter of the first positioning hole 211.
[0048] The connection strength between the positioning post 33 and the first base plate 21 can be enhanced by thread matching. When the hinge shaft plate 12 is sleeved on the second positioning part 332, it can provide sufficient support force to make the first base plate 21 and the hinge shaft plate 12 stably and horizontally fit together. At the same time, through the internal and external thread matching, the first positioning part 331 can rotate in the first positioning hole 211 and be adjusted to a suitable position, so that the second positioning part 332 is tightly engaged with the first base plate 21 on the outside of the first positioning hole 211, further enhancing the stability of the structure.
[0049] The fixing structure 32 includes a fixing hole 321 provided on the first substrate 21, and a fastener 322 for passing through the fixing hole 321 to fasten the hinge shaft plate 12 to the first substrate 21.
[0050] There is no single way to fasten the hinge plate 12 to the first base plate 21; other methods include screw fixing, welding fixing, or riveting fixing.
[0051] The fixing hole 321 and the first positioning hole 211 are arranged side by side on the end of the first substrate 21 away from the second substrate 22, and the hinge shaft 11 is located on the outside of the area where the hinge shaft plate 12 overlaps with the first substrate 21.
[0052] The fixing hole 321 and the first positioning hole 211 are arranged side by side, which helps the first substrate 21 to be subjected to uniform force when the hinge shaft plate 12 is fastened to the first substrate 21. The hinge shaft 11 is located on the outside of the overlapping area between the hinge shaft plate 12 and the first substrate 21, so as to avoid interference with the first substrate 21 when the door 20 rotates, which would affect the normal opening and closing of the door 20.
[0053] Reference Figure 3 The front wall of the housing 10 has a hinge clearance groove 4 extending through the thickness direction. The first base plate 21 extends from the hinge clearance groove 4 to the outside of the housing 10, and the second base plate 22 extends from the hinge clearance groove 4 toward the inside of the housing and is connected to the reinforcing iron 5 on the inside of the front wall of the housing.
[0054] During use, the hinge base plate 2 is subjected to tensile and shear forces transmitted from the hinge shaft plate 12. Unlike traditional front hinges that can only bear the load with fixing screws, the mating structure of the reinforcing iron 5 connected to the inner side of the front wall of the second base plate 22 in this application will also disperse the stress and reduce the possibility of deformation of the front wall and the box 10.
[0055] The following will explain in detail the connection structure between the second substrate 22 and the reinforcing iron 5:
[0056] Reference Figures 3 to 5 In one specific embodiment, the second substrate 22 is perpendicularly connected to the first substrate 21. The reinforcing iron 5 is provided with a slot 6 that cooperates with the hinge clearance groove 4 to allow the hinge substrate 2 to pass through. The second substrate 22 is provided to pass through the hinge clearance groove 4 and the slot 6, and is connected to the reinforcing iron 5 in parallel with each other, and is fastened to the side of the reinforcing iron 5 facing the inside of the box.
[0057] In this embodiment, the hinge base plate 2 is inserted into the hinge clearance groove 4 and the slot 6 of the reinforcing iron 5 in the front wall of the housing 10. The second base plate 22 is arranged parallel to the front wall of the housing 10 and abuts against the side of the reinforcing iron 5 facing the inside of the housing 10. The first base plate 21, which is vertically connected to it, extends from the hinge clearance groove 4 to the outside of the housing 10. The second base plate 22 and the front wall of the housing 10 and the reinforcing iron 5 are respectively provided with connection holes 221, and are fastened by screws passing through the front wall of the housing.
[0058] Of course, in some other embodiments, the second substrate 22 can also be fastened to the housing 10 by welding or riveting.
[0059] Reference Figure 8 In another embodiment, the hinge base plate 2 is integrally formed with the reinforcing iron 5 and is formed by bending the reinforcing iron. The hinge base plate 2 and the reinforcing iron 5 form an L-shaped integral structure, which is inserted into the hinge clearance groove 4 on the front wall of the housing 10.
[0060] The second substrate 22 is the portion of the reinforcing iron 5 located on the inner side of the front wall of the housing 10, connected to the first substrate 21. The first substrate 21 is perpendicular to the reinforcing iron 5 and is connected to the hinge shaft plate 12 along the extension direction of the hinge shaft 11. Thus, there is no need to manufacture the reinforcing iron 5 and the hinge substrate 2 separately, and the step of connecting and fixing the second substrate 22 to the reinforcing iron 5 is also eliminated, simplifying the process.
[0061] Reference Figure 9 In another embodiment, the reinforcing iron 5 includes a main body parallel to the front wall and a folding plate 7 extending perpendicular to the front wall toward the inner side of the box. The second base plate 22 passes through the hinge relief groove 4 and is connected to the folding plate 7 in parallel with each other, and is fastened to the bottom of the folding plate 7.
[0062] The second substrate 22 is provided with a connection hole 221 corresponding to the folding plate 7, and the second substrate 22 and the folding plate 7 are fastened together in the vertical direction by passing screws through the connection hole 221.
[0063] Of course, in some other embodiments, the second substrate 22 can also be fastened to the folding plate 7 by welding or riveting.
[0064] Because of the separate arrangement of the hinge main board 1 and the hinge base plate 2, the second base plate 22 can be pre-fixed to the front wall of the box 10 and foamed together with the box 10. During the manufacturing stage of the box 10, the hinge assembly 30 can be stably connected to one side of the front wall of the box 10. Subsequently, it is only necessary to fix the hinge main board 1 and the hinge base plate 2 installed on the door 20. The operation is simple and improves the efficiency of door installation.
[0065] In summary, the household appliance with hinge assembly of this utility model allows for more time-saving and labor-saving door installation. By setting a hinge shaft plate perpendicularly connected to the hinge axis, a first base plate that cooperates with the hinge shaft plate, and connecting the hinge shaft plate and the first base plate along the extension direction of the hinge axis through a connecting assembly, installation can be performed without opening the door, reducing the complexity of assembling the household appliance door, improving on-site assembly efficiency, and reducing labor costs.
